Use Pythagorean theorem:
\n" ); document.write( " $\"c%5E2+=+a%5E2+%2B+b%5E2\"$
\n" ); document.write( "Since T is the right angle, it means that RS is the hypotenuse\r
\n" ); document.write( "\n" ); document.write( " $\"25%5E2=+7%5E2+%2B+b%5E2\"$
\n" ); document.write( " $\"625=+49+%2B+b%5E2\"$
\n" ); document.write( " $\"625-49=+b%5E2\"$
\n" ); document.write( " $\"+576=+b%5E2\"$
\n" ); document.write( " $\"+sqrt%28576%29=+b\"$
\n" ); document.write( " $\"+24=b\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: ST=24cm \n" ); document.write( "
